Alright, buckle up, because this is a story, a weird one, about a question that popped into my head after a particularly chlorinated summer: “can you get pregnant in the swimming pool?” Yeah, I know, sounds crazy, but hear me out.

It all started with a bet. A dumb bet, I admit. Me and my buddy, Mark, were hanging out at the local pool, complaining about the heat. Somehow, the topic veered into the realm of ridiculous hypotheticals, and before I knew it, I’d wagered a six-pack that a girl couldn’t get knocked up just by swimming in a pool. Mark, the ever-contrarian, insisted it was possible, citing… well, he didn’t cite anything, just said he “read it somewhere.”
Now, I’m not a doctor, but I figured common sense would prevail. Dilution, chlorine, logistics… seemed like a pretty safe bet. But then Mark started planting seeds of doubt. “What if the water’s, like, right there?” “What if she’s super fertile?” The nagging voice of “what if?” started creeping in.
So, being the scientifically-minded idiot I am, I decided to “investigate.” I’m putting investigate in quotes because what followed was less about lab coats and more about Google searches and increasingly panicked texts to my sister who’s actually a nurse.
- Phase 1: The Google Deep Dive. This was mostly a black hole of clickbait articles and mommy blogs with questionable information. Lots of speculation, not a lot of science. I did learn a shocking amount about the resilience of sperm in various conditions (hint: it’s not that resilient in chlorinated water).
- Phase 2: Texting My Sister. This resulted in a lot of eye-rolling emojis and a lecture about responsible sex education. She did, however, confirm my initial assumptions: highly unlikely, bordering on impossible. But she also added the caveat: “Never say never.” Thanks, sis.
- Phase 3: The Pool Observation. Okay, this is where it gets weird. I spent a few afternoons at the pool, not exactly spying, but definitely observing the interaction between people and water. It felt creepy, I won’t lie. I even timed how long it took for a drop of food coloring to dissipate in the shallow end. Totally unscientific, totally pointless.
Here’s what I concluded (or, rather, reaffirmed):
It’s practically impossible. The concentration of sperm would be incredibly low, the chlorine would likely kill them off, and the sheer physics of getting them to the right place at the right time are astronomical. You’d have a better chance of winning the lottery while being struck by lightning, twice.

Did I win the bet? Yep. Mark begrudgingly handed over the six-pack (it was some fancy IPA he’d been eyeing). He still maintains there’s a slight possibility, but he’s also the guy who thinks the Earth is flat, so…
The Moral of the Story? Don’t make stupid bets fueled by boredom and the summer sun. And maybe lay off the internet for a while. Also, talk to your sister, even if she judges you a little.
